Adidas said it earned $9.7 million in the October-December period, down from $26 million a year earlier but still better than analysts' forecast of $5.4 million.

Revenue was up 19.2 percent, climbing to $4 billion from $3.4 billion and beating analysts' prediction of $3.8 billion.

The Germany-based company said that figure was helped by currency conversion effects, and global revenue was up 9 percent on a currency-neutral basis. It reported 15 percent growth at the Reebok brand.

A 3 percent rise in overall revenue in western Europe was topped by increases of 12 percent in North America and 11 percent in China.

Adidas North America reported a 13 percent currency-neutral sales increase for the quarter.

"This success," Adidas America president Patrik Nilsson said in a prepared statement, "was led by the momentum we are seeing in our key initiative such as our lightweight adiZero and Originals products."
